Description Bastien Nocera 2006-08-18 15:32:46 UTC

---8<---
SProcShmCreatePixmap() in file programs/Xserver/Xext/shm.c swaps all the multi-
byte members of the xShmCreatePixmapReq struct except for pid.  If the
application and the X server are running in different endianness, calls to
XShmCreatePixmap will fail.

This is difficult to reproduce unless you happen to have a locally running X
client in a different endianness mode to the server, but if you have and you
try to use XShmCreatePixmap the X server will return an error.
